Ceiling structure

The invention relates to a ceiling structure comprising a bearing beam and a main hanger. The bearing beam is fixed on a wall and is provided with a first hanging part. The main hanger comprises a bearing part and a second hanging part; the bearing part is used for holding a keel or is composed of a keel structure; the first hanging part is hung to the second hanging part; the main hanger is hung to the bearing beam. The keel is mounted in a hanging manner; after the bearing beam is mounted, the keel is directly hung; the complex operation where expansion nails are driven into a hanging rod one by one is avoided; the ceiling structure is convenient to mount and easy to demount after being mounted.
